[squid-users] Please help test a streaming problem through squid
Hello! We run squid as a caching proxy. No transparency or intercept in any form, and the only way out is through the squid proxy server. Web browsers use either wpad or hardcoded proxy configuration. Streams from www.dn.se/webbtv don't work. The commercial part first in every stream works fine, but when it's time to switch to the main stream it just stops and the screen goes black. Our production squid runs 3.1.21, and in a lab server I have tried with squid 2.7.STABLE9, 3.2.3 and 3.3.0.1-20121107-r12377. Same problem in all versions. The configuration in the lab server squids have been exactly as they were default installed, except that I enabled cache_dir ufs in all of them. Any ideas about this? (I will ask their support what the difference is in the streaming methods of the commercial part and the main part.) Thanks! -- Peter Olssonp...@leissner.se

Can you define "stream" in terms of the actual protocol taking place? There are many types of protocol involved with streaming. Squid only supports the HTTP and ICY streaming protocols. RTSP, RTMP, VoIP, VoD, SPDY and WebSockets streaming are not specifically supported by Squid (may require CONNECT tunnel access, but that is as close as it gets). and what agent is being used as a client? Sadly not all applets or embeded clients are capable of using an HTTP proxy. Amos

And the commercial part which works is played in the same plugin player as the main part which doesn't work. Maybe I'm using the word stream in the wrong way? Maybe video clip is a better phrase in this case? When I right click in the Flash plugin that is failing to play the video clip, it says "Qbrick Professional: 3.8.1.211" and "OSMF Version: 1.0", if that has any relevance. The Flash plugin in my web browser is version 11.3.300.270. These video clips are free to view so if you have a proxy squid available you could try them. I don't think they are limited to Swedish clients, at least I don't see anything about limitations on their web. http://www.dn.se/webbtv/ Thanks! -- Peter Olssonp...@leissner.se

If you can access the internet only using proxy you do have problem since flash dosnt really support proxy settings. There might be a way to create an rtmp proxy to use CONNECT for RTMP but it's a very big thing.

Flash web clips work fine behind proxy for these commercials, and also for complete video clips on other webs. -- Peter Olssonp...@leissner.se

If you are willing to capture the sessions with WireShark or tcpdump (filtered) I will be happy to take a small look at it.

I assume that the outside of the proxy is the most interesting to capture? Peter Olssonp...@leissner.se
